Conviction

2022–2026-04-30

Attempt to withdraw guilty pleas rejected by Court of Appeal

Conviction

Tarrant belatedly sought to withdraw his guilty pleas, claiming prison isolation and his psychological state had made them involuntary. Following a hearing in February 2026, the Court of Appeal rejected the attempt on 30 April 2026, finding no credible evidence supporting the allegation of coercion or incapacity.
